Title: Mowing cutter for agricultural soil-cultivating machines
Inventor: FLECK ALFONS
IPC: A01D75/18
Filed: 1981-11-06
Abstract: In a mowing cutter (1) for agricultural working machines, each fly cutter (8) is assigned a baffle plate (11) which is supported above this on the cutter carrier (7) and which is arranged behind the fly cutter (8) in the direction of rotation. The baffle plates can be held flexibly, so that they can shift aside automatically when an obstacle is encountered. The baffle plates (8) ensure that the mown material is not wound on the bearing sleeve (3), but instead is thrown out immediately after the mowing, so that bale formation is prevented and a uniform flow-off of the mown material is guaranteed. <IMAGE>
Patent DE-3149548-A1 (DE)
Inventor: GREBE GERHARD
IPC: F23H11/00
Filed: 1981-12-15
Abstract: A traveling grate for a furnace. The grate is formed of plural pipes through which flows a cooling medium, in particular water. The grate also includes plural movable chains. Grate plate guide flanges are arranged laterally on the pipes. The guide plates, which are connected to the chain rest on the guide flanges. The upper strand of each movable chain is guided in an additional chain guide. The lower strand serves to move ash which has fallen through the grate away to a collection station. Due to the heat discharge through the pipes, the heating performance of the grate can be increased or at a given heating performance an elevated life span can be achieved. Fluid which can be heated up in the pipes can be used profitably, for example to preheat boiler heat.

Patent DE-3202607-A1 (DE)
Title: Broadcast receiver
Inventor: TOMOHIRO RYO
IPC: H03J7/02
Filed: 1982-01-27
Abstract: The described broadcast receiver comprises a tuner (12) connected to a level detector (20) and a distortion level detector (24). On detecting a tuner output signal which does not lie above a predefined value, the level detector (20) sends a tuning instruction signal to a control unit (22) in which this signal is set to "wait" and which feeds a waiting signal to an AND gate (28). If the distortion level detector (24) detects a distortion level from the tuner (12) which does not lie below a predefined value and a timer (26) identifies that the distortion level has a predefined duration, a distortion signal is sent to the AND gate (28). Depending on an output signal of the AND gate (28), the control unit (22) sends a tuning signal to the tuner (12) to change the latter's tuning frequency until it is tuned to a broadcast transmitter with good reception and distortion levels. While the tuning frequency is being changed, the broadcast receiver remains muted under the control of the control unit. <IMAGE>

Title: Process for the production of ammonia synthesis gas
Inventor: MECKEL JOACHIM F
IPC: C01B3/02
Filed: 1982-02-24
Abstract: A process is described for the production of ammonia synthesis gas from a starting gas having a high hydrogen content, such as coke oven gas, which is catalytically/autothermally reformed with an oxygen-containing gas, for example air, to give a cracked gas containing carbon monoxide and hydrogen, hydrogen being removed from the starting gas, prior to its reformation, by means of a multistage pressure swing adsorption plant (PSA plant) and then mixed back into the main gas stream, for example the synthesis gas. To simplify the process, only the gas flushed from the PSA plant is subjected to the reformation and then to conversion, a carbon dioxide scrubbing and a methanation.

Patent DE-3236975-A1 (DE)
Title: Simple distillation of fatty acids
Inventor: STAGE HERMANN DR
IPC: C11C1/10
Filed: 1982-10-06
Abstract: The present invention describes a process for the simple distillation without stripping steam of crude fatty acids which contain a fatty acid mixture which is to be vaporised and consists of saturated and unsaturated fatty acids, and non-vaporising fats and impurities, wherein the vaporising fatty acid mixture predominantly consists of acids of a C number range which comprises a maximum of three consecutive C numbers. It is based on the object of considerably reducing the energy required for distillation processes of this type. This is achieved according to the invention by dividing the main stage of the distillation into a first and a second part-stage, by partially vaporising, in the first stage which has a continuous flow vaporiser, the fatty acids which are to be distilled off, at temperatures and pressures which are higher than the temperatures and pressures in the second part-stage, by using the vapours originating from the continuous flow vaporiser as heating vapour for the second stage, and by carrying out the vaporisation of the free fatty acids in the second stage with a vaporiser operating with forced circulation until a required final acid number is reached.
Patent DE-3238874-A1 (DE)
Title: Arrangement on a three-stage temperature switch, preferably for water heaters
Inventor: BRAATHEN THOR FROELICH
IPC: H01H89/04
Filed: 1982-10-18
Abstract: A three-stage temperature switch, preferably used for water heating, has regulator contacts (1 and 2) in the first and second branches of the switch, the operating thermostat (A) and the safety thermostat (B) being connected to the housing (C) of the three-stage switch, in order to maintain an operating temperature by making and breaking an electrical circuit via an operating contact (5) in the L-branch of the switch, and monitoring a higher, critical temperature for breaking the electrical circuit via switch contacts in the first, second and L-branches of the switch, when the critical temperature (e.g. 95 DEG C) is exceeded. The switch contacts are formed by the regulator contacts (1' and 2') and by a switch contact (3) in the L-branch. These three contacts can be operated simultaneously by an adjacent element (4) which is in mechanical contact with the safety thermostat (B) and is moved by said safety thermostat (B). If the above-mentioned critical temperature is exceeded, the safety thermostat (B) snaps out of its operating position into a reversed position and hence opens the contacts (1', 2' and 3) and isolates the heating element of the water heater. The three-stage switch is provided with a reset key (6) for resetting the safety thermostat (B) into its non-reversed operating position and hence for closing the contacts (1', 2' and 3). <IMAGE>

Patent DE-3303599-A1 (DE)
Title: Directional control valve
Inventor: LEUTNER VOLKMAR DIPL ING
IPC: F16K37/00
Filed: 1983-02-03
Abstract: The invention proposes a directional control valve (11) with an additional position, in which separation from the working pressure and thus a zero correction of a pressure sensor (41) is possible. For this purpose, a housing web (22) of the directional control valve (11) has two annular grooves (36, 37). Via these and a longitudinal groove (44) in the spool (23), the pressure sensor (41) is relieved to a tank (39). Thus, in this position, there is no longer any pressure on the pressure sensor (41) and each measured value deviating from zero at this point in time can be recognised as a so-called zero error. It is thus possible, with little outlay and without additional switching means, to perform a zero check and a zero correction at the pressure sensor (41) during the control operations. <IMAGE>

Patent DE-3321962-A1 (DE)
Title: Luffing lever
Inventor: KONKART HANS
IPC: B63B35/79
Filed: 1983-06-18
Abstract: The luffing lever is a supplementary device between the bottom mast end and the mast foot for dinghies without a foresail, with a sail area disposed on one side relative to the longitudinal axis of the boat and therefore also suitable for surfboards. It shifts the mast to the windward side by rotary movement about the longitudinal axis of the mast foot, the mast foot remaining at its preset location. The windward-side part of the sail area thereby forms a turning moment with opposite direction of rotation to the turning moment, reduced to the same degree, of the remaining sail area. The result is a reduction in the yawing when sailing to windward.

Patent DE-3327380-A1 (DE)
Inventor: KAHN KLAUS-DIETER
IPC: H04J3/12
Filed: 1983-07-29
Abstract: The invention consists of a method for bitrate transformation of digital signals in digital transmission systems in which additional bits are inserted in the digital signal before transmission at the transmitter and then removed again at the receiver. For this purpose a clock pulse is to be generated for writing into and reading out from a memory with address counters, and there must be no systematic pulse jitter. For this purpose the invention provides that on the transmitter side, the clock oscillator for the read-out pulse is phase-locked to a value m/n times the frequency of the clock pulse for writing into the relevant address counter. On the receiver side, the clock oscillator for the read-out clock pulse is phase-locked to a value n/m times the frequency of the write clock pulse. <IMAGE>
